CV

I take on IT projects from idea to final result 🎯. I can do frontend 💻, backend, and unusual tasks too. I enjoy working when there’s a clear goal — no bureaucracy, no endless calls.

Whether it’s a website form or API automation — I’ll handle it. I use the right tools to work fast ⚡, efficiently, and simply. What matters most: it works, looks neat, and makes the client happy 😊

I work responsibly, stay in touch 📱, and respect deadlines ⏰. I can help shape the idea, solve the problem, or just get the job done well. I like turning messy tasks into clean results 🚀

Message me — we’ll discuss, I’ll do it, and deliver on time.

  • Creating a payment button using API for a Shopify store

    Javascript and Typescript
    Creating a payment button using API for a Shopify store — example of freelancer's portfolio work in category Javascript and Typescript
    The client approached with the task of connecting a non-standard payment provider to Shopify. The provider only had an API but did not have a ready-made app or integration for Shopify.

    I wrote a script that redirects the customer to the payment page after placing an order.

    … Everything works stably, the solution is fully compatible with Shopify. The client can now accept payments through their payment service without extra steps and third-party apps.

  • Dashboard with automatic estimate for online store

    Databases & SQL
    Dashboard with automatic estimate for online store — example of freelancer's portfolio work in category Databases & SQL
    I have completed the backend and frontend. Using the API, the script retrieves advertising expenses and orders, also accounts for operational costs, and based on all this, calculates the estimate. All data is written to a Postgres database, so you can view data for any period. There is a currency change, interface settings for each project separately, and some additional functions. It works completely autonomously and saves the client a lot of money on the estimate. It turned out to be a very convenient service.
